PROJECTILE.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed November 27, 1914. Serial No. 874,284.

To all whom it may concern.

Be it known that we, JOHN JOSEPH Sronnn and Franz H. SAUERMANN, respectively a citizen of the United States, residing at Brooklyn, in the county of Queens the following is a specification.

This invention relates to improvements in projectiles, such as are adapted to be dis charged from the barrel ofa gun of any prefererd type in an ordinary manner, the object being to combine with the projectile means whereby it may be more efiectively used in causing damage to air craft having vanes of considerable area, or gas holders, which if punctured, would cause disablement.

, Another object is to provide such projectiles in forms which necessitate no change in the guns whatever or methods used in the processes of loading or discharging them.

These and other objects, such as the maintenance of the proper weight, accuracy of flight, bursting capacity and extended scope of usefulness, are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming part of this specification, and in which Figure l is a side elevation of a projectile, partially in section, made in accordance with the invention. Fig. 2 is a transverse sectional View, taken on line 2-2 of Fig. 1. Fig. 3 is an enlarged sectional View of the automatic internal discharge. means, and, Fig. 4 is a perspective view of the constraining ring.

In the drawings, the projectile body 10, is shown to be of the usual elongated cylindrical type, with an ovoid point 11, and a recessed interior 12, for the bursting charge, held normally by the cap 13. A number of uniformly spaced recesses 15, four beingindice-ted, are formed longitudinally in the body 10 of the projectile, the recesses being suited in length, depth and width to receive the arms 16, which may preferably be formed with corrugations 17, and hook ends 18. These blades are pivoted at their rear ends on the pins set in the cars 21 and 22, formed by removing material from the body parallel laterally with the arm recesses, at each side thereof and at the rear as at 23 and 2a. The purpose of these blades is for cutting wire, asnetting and the like, obstructing their passage and making a greater aperture through the same than would a plain projectile.

In order that the arms may be extended outwardly, at right angles from the body when in operative position, that is immediately upon discharge from the gun, springs 26 are used. A band 28 is preferably made of thin sheet aluminum, formed with a stifiening "central rib extending its full length, having a slgt 29, near one end and a tongue element 30, engageable therewith at the other end so that the band, as an entity, can be easily and rapidly removed; this constraining band is removed when the projectile is loaded into the gun.

Bored longitudinally into the rear of the projectile are round openings 32, reduced continuations of which enter the recesses 15, each containing a firing pin 33, having a shoulder 34, pressed toward the recess by means of the coiled spring 35, the lower part, 37 of the firing pin extending through it and a fixed washer 36 against which the spring rests; the function of the spring is to prevent a premature action of the blades in detonating the projectile before it has come in contact with a relatively rigid obstruction.

A percussion cap, detonator or fuse 38, is arranged in register with the inner part 37, of the firing pin and held in place by means of a tube 39 secured in the opening by" the cap screw 40. WVithin the tube is contained an explosive, as for instance, a stick of smokeless powder 41, the tube having an elongated opening 42, registering with a explosive within the chamber 12 causing the projectile to burst, disrupting whatever it may have encountered.

As the arms are uniformly spaced and extended the trajectory of the projectile is imperceptibly affected, While the probability of making a hit is largely increased thereby rendering its employment particularly effective as against air craft.

Manifestly the invention may be made in any desirable caliber to suit the rifles of infantry as well'as heavier and more powerful ordnance and that it may be combined with numerous forms of projectile bodies; also that minor modifications may be made from the design indicated, without departing from the scope of the claims hereto appended Having thus described our invention what we claim as new and desire to secure by Let-' ters Patent, is

1. In a projectile, the combination with a hollow integral body of a plurality of saw toothed, knife edged hook-ended arms nor mally contained within said body, a metal lic strap, having engaging ends, surrounding the said body and arms, powder chambers at the rear of said body in alinement' with each of said arms, firing means combined with each powder chamber, saidjiring means being operable by the movement of said arms and a central powder. chamber communicating with the first named powder chambers.

Gopies of this patent may be obtained for 2. In a projectile, the combination with an elongated body having a powder chamber extending therewithin, of a plurality of knife edged arms pivotally secured within recesses insaid body, an auxiliary powder chamber, rearward of e'achof said arms, a, firing means combined therewith, said firing means being operable by said arms, detonators for each firing means, sleeves contain.-

ing said detonators, means for removably engaging said sleeves Within said body and passage-ways extending between said firing means and said main powder chamber.

3. In a projectile, the combination with a longitudinally recessed, hollow body, con- ,taining an explosive, of a plurality of hook ended arms pivoted in the mentionedrecesses, springs adapted to move said arms outwardly when released, a plurality of firing devices set at the-rear of the recesses,-

means combined with said arms for operat-' mg said devicesand means commun cating between the explosive chamber in said hol low body and said firing devices whereby five cents each, by addressing the "Commissioner of Patents, Washington, D. G.
